That is unfortunate.

As far as OE goes, it's fairly easy: you just set
PREFERRED_VERSION_linux-libc-headers appropriately.  But, if Angstrom
has taken a distro decision to use the 2.6.31 headers then you will have
a problem: if you just make that change for one MACHINE, your binaries
will now be different to everybody else's and hence what you are
building is not really Angstrom anymore.

If you are not willing to fix glibc then I think there are only three
sensible ways to proceed:

a) update your machine to use the 2.6.31 kernel so that the problem goes
away; or

b) persuade the Angstrom maintainers to adopt 2.6.24 headers as their
DISTRO standard, though this will presumably cause some fallout in terms
of other incompatibilities so I suspect it will be a struggle; or

c) create your own DISTRO, which can be a derivative/fork of Angstrom if
you wish, and in which you can obviously do whatever you like.  This
probably seems like a bit of a large hammer to crack that particular nut
but it is more or less the only way in which you can use a different
version from the other Angstrom folks.
